An existing drug, re-engineered to target lung cancer cells.
PimoTarget loads the repurposed drug pimozide into lipid nanoparticles and spray dries them into a powder. It aims at non-small cell lung cancer, where better drug targeting is needed.
Lung cancer needs better-targeted drugs
Non-small cell lung cancer remains hard to treat with drugs that reach the tumour well.
Limited targeting
Many drugs do not concentrate where they are needed in the lung.
Free drug falls short
Pimozide on its own was less potent against A549 cells than the lead nanoparticle formulations.
Loading is uneven
Not all lipid carriers hold the drug equally well: solid lipid nanoparticles barely exceeded 70% encapsulation.
Lipid nanoparticles, dried into a powder
PimoTarget combines a high-loading lipid carrier with spray drying to give a powder form of pimozide.
Nanostructured lipid carriers
- Highest loading of the three types
- Attributed to oleic acid
- NLC 4 and NLC 5 among the leads
Spray dried powder
- Made by a microemulsion technique
- Converted to powder by spray drying
- Moisture sorption and morphology assessed
Stronger than free drug
- Tested on A549 lung cancer cells
- NLC 4, NLC 5 and LLC 5
- Biphasic drug release pattern
How PimoTarget is made
A four-stage laboratory process.

Microemulsify
The nanoparticles are formed by a microemulsion technique.
Microemulsion - 3
Spray dry
The dispersions are spray dried into powders, shifting particle size from nano to micro scale.

Test on cancer cells
Encapsulation, release and anti-proliferative activity against A549 cells are measured.

What the laboratory study showed
In vitro characterisation and cell-based testing on A549 non-small cell lung cancer cells.
| Carrier | Reported finding |
|---|---|
| Nanostructured lipid carriers (NLC) | Highest encapsulation, approximately 96% ± 2.1% |
| Solid lipid nanoparticles (SLN) | Encapsulation barely exceeding 70% ± 2.5% |
| NLC 4, NLC 5, LLC 5 | Lower IC50 than free pimozide on A549 cells |

Where the evidence stands
PimoTarget is at the earliest research stage.
Cell studies only
Activity was measured in A549 cells in the laboratory, not in animals or people.
Targeting still to prove
Delivery to lung tumours in a living body has not yet been shown.
Safety unknown
Safety of this formulation for cancer treatment has not been studied.

Frequently asked questions
What is pimozide?
It is an existing drug that PimoTarget repurposes and tests against non-small cell lung cancer cells.
Why lipid nanoparticles?
They can carry the drug efficiently. Nanostructured lipid carriers held about 96% of the drug.
Why spray dry them?
Spray drying turns the nanoparticle dispersion into a powder. Particle size shifted from nano to micro scale in the process.
Did it work better than the plain drug?
In cell tests, three lead formulations showed lower IC50 values than free pimozide against A549 cells.
Is this a cancer treatment today?
No. It is an in vitro research stage project with no animal or human data yet.
